LC0 doesn't think white has much more than 60% (a variety of ways), seems to do reasonably on the database so it passes the basic tests

Bc5 iso Nc6 is definitely the idea from the database.  

Honestly it strikes me to some degree as a trap in that 5 Nc3 isn't great, but unfortunately 5 Nc3 Bc5 appears liable to end in a lot of very fast forced draws.

White is seemingly a bit better after c3, Nb3 etc but nothing tragic. 

You'll want an answer you're happy with after 5 Be3. 5.. Qxb2 is going to need some study to be happy defending it and 5.. Bc5 6 Na3 is seemingly pleasant for white and has several games in the database.
